📋 Description

• Own the security configuration of our identity and collaboration stack: identity and access policies, third-party app governance, DLP, context-aware access, and admin audit. • Build, tune, and maintain detections. Design response playbooks for high-signal alerts. • Harden our cloud footprint, Kubernetes clusters, and CI/CD pipelines. • Own the security posture of the endpoint estate, including MDM configuration and endpoint telemetry. • Lead and participate in security incident investigations end-to-end. • Run threat models and architecture reviews for new internal systems and infrastructure changes. • Work alongside Protocol Security, DevOps, IT Ops, and Product Engineering to raise risks constructively.

🎯 Requirements

• 5+ years of hands-on infrastructure or detection-and-response security experience. • Production experience securing a cloud-based identity and collaboration platform at scale, beyond default settings. • Hands-on experience with a modern SIEM and SOAR: writing detections, onboarding log sources, building response playbooks, and tuning to reduce false positives. • Strong cloud security background, including IAM, network controls, workload identity, and organization-level guardrails. • Practical experience securing a macOS-dominant endpoint fleet: MDM, endpoint hardening baselines, and EDR. • Familiarity with Infrastructure as Code, secrets management, and security automation. • Real incident response experience. You've been on-call for security and led investigations to conclusion. • Clear, constructive technical communication across engineering and non-engineering stakeholders.

🏖️ Benefits

• Freedom & ownership culture: no time tracking, minimum bureaucracy-only results matter. • Remote‑first: work wherever you’re most effective; optional travel to team or industry events.
